minerals. >> where the road ends is where the trouble started. >> we get a chance to see ground zero. this is the entrance to the mine that blew out last wednesday. >> it was a mine entrance dammed by a landslide. work crews were probing, trying to figure out how much water wag built up behind it. the gallons burst out of the mountains and flooded into the rivers. the e.p.a. built pods for the run off, around the hole and around the corner of the mountain. agency administer visited nearby dewar anningo on wednesday. >> i came from a briefing that dave and others provided to me on the status of the clean-up, and the status of the monitoring of the plume. i am excited that they are fully operational, and we are working this issue very hard.
>> we came to the accident site with a member of the incident management team, and several congressional staffers getting their first look. and with steve, an engineer with 40 years in mining who doesn't think happened here should signal an end to the mountains. >> what are the opportunity for more mining? >> we didn't comply with the rules. even in today's market, metal prices can work. >> we can see mining grow in the silver tonne area. >> yes. some could start it again. >> chances of future mining could disappear if it's designated as a toxic clean up side, something many downstream would like to see. that could bring clean-up money. it's a contentious issue here, for the super fund label could
slow development, and kill the tourist trade. silverton's true goldmine. >> this is where the flow came down. the guide represents the city and county as a spokesman. the funds from the national priority list may come quickly or take decades. and if the 2 for 1 site is on the community, it could be devastating for the people that live here. >> this hole in the ground is not gushing sludge. but other nearby mines leak contaminated town water at hundreds of gallons per minute. it happened for years and super fund or no super fund. it's a small win stretching into the future? >> the e.p.a. says the toxic spill is dissipating, glutens

spills into the rivers, a body providing drinking water, lake powell is not safe. those that work to protect lake powell are not worried about the instantaneous effect. what they are worried about is what they can't see, the build-up of minerals and chemicals, and mines from the rivers, the san juan river, everything that needs into lake powell. this goes down of the river, and will land in the sediment delta, and the san juan arm and will stay there, get locked up in there. if the lake goes up and down, the river can cut in, and release the touch back to the lace. when we need long-term modelling to understand the full implications of this time.
what are the effects, two generations from now. >> they are high. they have individual effect on humans and other organisms, and native fish and their eggs exposed to this. and things like that. the metals are bad news. we don't want any contacts in them. >> this event doesn't seem to pose a threat to anyone else. it's the cumulative effect. event endanger a fragile eco system and the millions that depend on it. when you think about a crisis like this, you can't think in the immediate terms. there's no light where it says past this point it's dangerous. there are secondary and tertiary effects that people are worried about. for instance, if, in fact, they stopped fishing in this place, if it's dangerous to do so, that

enlisting celebrities. it true attention. i guess it backfired. >> a lot have concerns about women and children. how do you prict sex workers from getting in a situation that is dangerous. >> well, of course the amnesty international policy discusses that in detail, and came to the conclusion that as a matter of fact decriminalization is what protects people, sex work from exploitation, protections from the police, protects their right to move, to associate. at this point. if you are a sex worker and you work with friends. you can be prosecuted to work together. >> the laws are ridiculous. we'd like to move things to protect safety and health.
does that work? >> well, that needs to be looked at in an historical context, and the need of decriminalizing aspects in an effort to protect sex workers doesn't work. they don't have time to screen them on the streets. the work place is illegal, and underground. so, again, they have no recourse or ability to organise, it pects mare alth and safety. >> explain the nation, decriminalizing sex work, what it could look like. what does it many in terms of deorganising. the new zealand model is the one we look towards. in that model one uses
